The office called to inform me a technician was on the way. He arrived a few minutes before I even got to the residence to be serviced. He was professional, punctual and got right to work. Brian was efficient, polite and got the job done. He offered suggestions and asked if I had questions. The job sheet was handed to me for signature , he gave me a copy and was on his way! Good service!

Courteous, friendly and professional. They installed the system a couple of years ago and I have had them do the maintenance since. No complaints at all.

This was the first time we used Mr Furnace. CJ was the young man that came to do our maintenance. He was very polite and explained everything to me. He answered all my questions and was very truthful. Thank you Mr Furnace for having great employees.

I called Mr Furnace about a problem with my furnace thermostat. They responded quickly, professionally; and finished in a very timely manner. The technician was very knowledgeable and his work truck was stocked with all he needed to complete the job. I was very pleased.

The fellow inspecting my air conditioner was on time. He kept the place spotless and took all the time needed to thoroughly check out the system. He left me with good advice. He was personable and professional. As usual, it was a pleasure.
